+## Building and Running
+
+### DesktopVK (Cross-platform)
+
+#### Before Building
+
+* Goto https://github.com/MonoGame/MonoGame/actions and find the latest run that was built the `develop` branch.
+* Download the binary artefact, which will have a name with a similar format to `MonoGame.3.8.*4*.*-develop`
+* Extract that directory as a top level folder of these samples. eg. if you downloaded `MonoGame.3.8.4.2908-develop` the not level folder name should be `MonoGame.3.8.4.2908-develop` and within that will the extracted contents of you artefact your downloaded.
+* Currently the VK csproj looks for `MonoGame.3.8.4.2908-develop`, so you may need to edit the *VK.csproj to point to which ever artefact you downloaded and unzipped.
+
+#### Building and Running
+If the above went well, execute the following command in the top level directory of this sample.
+
+```
+dotnet run --project Platforms/Vulkan/CollisionSample.DesktopVK.csproj
+```
+
+
